GEAR-ING.

Specification of Letters Patent.

Application led March 16, 1905. Serial No. 250,488.

'[0 all I2li/1,0m 'it may concern Be it known that I, OLivnn M. EDWARDS, a citizen of the United States, residing at Syracuse, county of Onondaga, State of N ew York, have invented certain new and useful Improvements in Gearing, of which the following is a full, clear, and exact de,

scription, reference being had to the drawing accompanying the same.

. My invention relates generally to the manufacture of gear brackets and has for its objects to provide a bracket adapted to be applied in different desired positions relatively to a window, to construct the gear in parts, to construct the casing in sections, preferably from sheet metal, suitably formed to receive the working parts, and hold them in position when the sections are secured together and also to cheapen the cost of manufacture; and it consists in the combinations of parts or devices hereinafter set forth and particularly pointed out in the claims, which form a part of this specification.

Like letters of reference, wherever they occur, indicate corresponding parts in the several figures of the drawing.

Figure 1 shows in front elevation one embodiment of my invention with a part of the casing broken away to'show the engagement of the worm with the gear, as in the case where the bracket is made to serve the purposes of the gear bracket shown andv described in Letters Patent No. 667,302, Feb. 5, 1901. Fig. 2 shows a blank before'being bent into the desired shape, which forms the section or part of the casing which, as here shown, is secured to the window frame or other structure where the bracket is to be used; Fig 3 shows this same blank after being bent into shape, with portions upstanding to form. the sides and portions of.

the ends of this section of the casing; Fig. l shows a longitudinal section on line 4 1 of Fig. 3, illustrating the form of the journal bearing for the gear formed in this section; Fig. 5 shows a blank, before bending, which may form the top or other section of the casing; Fig. 6 shows this blank after being bent into shape with its side and end portions upstanding. so as to receive the side and end portions of the other section: Fig. 7 is a longitudinal section on line 7 7 of Fig. 6, illustrating the journal bearing for the gear in this section of the casing;

Fig. 8 shows the portion of the gear bearing the teeth, which portion may be formed, if desired, by punching the same from a piece of material of substantially uniform thickness; Fig. 8 shows in edge view this gear portion seen in Fig. 8; Fig. 9 shows in end view one form of another portion of the gear, illustrating the central opening which receives the shank of the roller or other device to be mounted in the bracket, as well as that portion which receives the gear portion seen in F ig. 8; Fig. 10 shows in side elevation the portion seen in Fig. 9 and illustrates one of the journals to be received by one section of the casing; Fig. 11 shows in end view another portion of the gear containing the other journal and to be received by that portion which receives the gear portion; Fig. 12 shows in longitudinal section the assembled parts, illustrating the preferred form of securing the two sections of the casing together' and of thereby holding all of the working parts in position; Fig. 13 shows in side elevation the bracket seen in Fig. 1, with a portion of the top or receiving section of the casing broken away to illustrate the relation of the parts and also of the manner of bending over of certain portions from the positions seen in dotted lines to those seen in full lines to secure the working parts in position; Figs. 14, 14 and .141 illustrate another way of securing the two sections of the casing together; Fig. 15 illustrates in end view a tube which may be employed to re ceive the shank of the roller to be supported by the bracket and also the other portions of the gear.

The casing, as herein shown, is preferably formed from sheet metal or similar material adapted for bending into partial borI form, and which may be formed in the de sired shape by punches and dies, as is well known. lith such material journal bear ings may be readily formed of any desired extent of bearing surfaces for the journals which are to work therein, for instance as indicated in Figs. /l and 7. These bearings are preferably formed while the blank is flat and before the side and end portions are bent up by well known means. l

The casing A, as shown. is formed in two sections o and c', preferably of sheet metal, by any desired means of suitable dimensions to receive the intended parts and be manipulated into the desired shapes. The sec- Patented J an. 5, 1915.

tion a of this casing A, When in the form seen in Fig. 2, is provided With ears by vvhlch the bracket may be secured in position, and has formedV in it the journal bearing a" to receive one journal of the gear andl also the bearings y to receive the Worm B,

When the side portions of this section a are bent, as seen in Figs. 3 and Ll. As here shown there are two angular or projecting side portions e e and tivo angular or projecting end portions e2 e3, to be bent up at substantially right angles to the remaining or main portionsA which are preferably substantially flat and of rectangular form. This section, as a, may be ofA any, desired form or shape adapted to serve the purposes served by the specific shape shown herein, that is, of any shape adapted to receive the Working parts and to be secured in different desired positions relatively to a Window.y The section a of this casing A also has a journal bearing m and bearings y g/ to receive the gear and Worm, respectively, the same as those formed in section a. The tWo sections `are preferably duplicates of one anotherl in respect to these bearings Which receive these parts. This section a also is preferably provided with two angular or projecting side portions e4 e5, and two angular or projecting end portions, e e7, Which may be bent up at substantially right, angles to the remaining or main por-y tionsandare preferably bent so as to form s side and end portions adapted to receive the l side and end portions of thesection a, as

indicated in Figs. 12 and 13. Preferably this section a has formed on its side and end portions clenching pieces es e9 en andl e, Which extend beyond such side andend portionsand areto be bent over to embrace the under 'portions of the section ci and clench or secure the tWo sections together, as indicated in Figs. 12 and 13.

1f desired instead of having these casing pieces of sufficient length to bend over and clench the two sections together, as shown in Figs. 12 and 18, they may be otherwise made, for instance, so that the portions, vas` 62 of section @may pass through opening @21 in section a and rivet or clench as indicated in Figs. 14, 14a and 14S?. The portions of section a. in Which the slots 621' are formed are separable from adjacent portions by. slits e2? thereby forming portions 623 Which are to be bent up into the form seen in Fig. 14 and servethe same. functions as are served by the .portions e2 inpreceding figures.

The Worm B may be formed by any desired means, andprovided with any desired shape o r form of end portion or portions by Which.such Worm may be.y conveniently rotated.r As shown thispvvormis provided With elongated squared and Yslotted Aend portions b, b', Which may be taken'hold of "to rotate the Worm, or, if desired, a tool of suitable shaped engaging portions, as a screwdriver or Wrench may be used in connection With such ends to rotate such Worin, andthereby rotate the gear. Suitable shoulders, as b2 and b3, are formed adjacent to such squared or slotted ends which engage With the exterior surfaces of the side portions 64 and e5 of casing section a and prevent undue end motion of such Worm in its bearings in the casing by lthe end thrust given to the Worm by the gear C in forcing suchv gear to rotate. The end portions of this Worm are shown as duplicates of one another, so as to be received in the casing With either end pointing in a given direction. It is of course obvious to any mechanic that either a screwdriver or suitable Wrench may be employed on the specific end portions of this Worm B here shown and also that either the slotuor square end portions can be used ivith like effect and that When the slot is employed without the squaring of such portions the screwdriver alone would be used. This gear C, as here shown, is composed of three parts or portions, the gear portion c, the receiving portion c and loose journal portion 02. The gear portion c, as here shown, is made with substantially straight teeth and is therefore adaptedto be placed either side up on the receiving portion c, in assembling the parts together. Furthermore this gear portion c may be formed by punches and dies into the form herein shown, if desired, and the cost of making each individual portion be very much reduced over what would be the case by forming such portion by other means adapted to give equally good Working results. Of course Ithis portion c may be formed otherwise than asj ust described, but the above is the preferred Way.

The receiving portion c is shown in Figs. 9 and 10, as being formed integral With one of the journals c? and with a central opening the Whole length of this portion c, which opening is adapted to receive the shank of one end of a shade roller or similar formedrpartr and to prevent the same turning therein and causing such shank portion to 4,rotate with the gear C of which this portion c forms a part. j A portion of this part c is provided with the journal c3 which is adapted to be receivedin one of thev casing sections journal bearings m and and it ,has aI shoulder to prevent its outward movement from the casing A in an endvvise direction, as indicated in Fig. 12. The journal portion c2 is formed with a journal bearing and shoulder corresponding to that on portion c and is received by this latter portion and holds the gear C from endvvise motion in one direction, yalso as is indicated in Fig. 12, Where this l gear C is shown in longitudinal section With the parts assembled in place and the worm B seen in cross section. It will be obvious to a mechanic that the construction of this casing ready to receive the working parts will be the same whether' each of suoli parts (worm and gear) is made from one piece of material or of different pieces, for in each case they are received by the casing as a single piece.

Instead of making the journal and tubular portions of the receiving portion c from one piece of material they may, if desired, be otherwise made, as for instance of two pieces, one tubular and the other a substantial duplicate of the loose journal portion c2, seen in Fig. 1l, which is to be forced onto the tubular portion c5, seen in Fig. l5, in a well known manner of forcing one piece of material onto another piece, so that the two may act as a single piece would act. It is preferred that these gear parts shall be formed so as to go either end up in the assembling of the same in the casing, but

' they may be constructed in any desired man` ner, so long as the gear as a whole may serve the functions served when constructed as herein shown.

Then constructed as herein shown, to as- -semble the parts and secure the working parts in position, it is only necessary to take a casing section a', as shown in Fig. 3, place a gear C, either end up, in the journal bearing m', a worm B in bearings y y and then take a casing section a, as seen in Fig. 6, and place it, with its angular or projecting side and end portions et, e5, e and e7 pointing toward the side and end portions e, e, c2 and e3, so as to receive the same and force the two sections toward each other and cause the journal bearing in section a, to receive its .journal end bearings y y receive or pass over the journal portions ofV the worm B with the shoulders b2 and b3 of this worm outside of the side portions e* and e5 of casing section a, all as seen in Fig. l. Then by bending over the clenching pieces es, e, el@ and en, as indicated in Figs. l2 and 13, the two sections of the casing A are firmly secured together and the working parts, worm B and gear C, are secured in working position. This construction of casing, worm and gear permit of the structure, as a whole, being mountedr in'different positions with suitable access given to the worm to operate and actuate the gear to the desired extent. For instance the casing and combined parts may be used at either the right or the left side of a window with equal facility, or they may be used with the worm substantially at right angles or parallel with the direction of movement of the sash in opening and closing the windows, or in any other direction desired to give ready access to the worm to operate the same by hand or a tool suitable for the purpose.

It Will be obvious to a mechanic that the ear portions by which the casing, as A, is secured in position may be of any desired shape and arranged in any desired manner relatively to the other portions of the casing, so long as they are adapted to hold such casing in place in the particular position or positions it is desired to place it.

That which is herein set forth will naturally suggest to those skilled in the art changes or modifications in what is shown and described, but I' desire to include within my invention all constructions which come within the spirit thereof and have the parts combined together with the mode of operation herein set forth and particularly pointed out in the claims forming a part of this specification, and, therefore, I do not wish to limit myself to that which is herein specically shown and described.
